The three-acre property also has a c. 1890 barn and a c. 1920 cottage.","why_significant":"The nomination argues the mansion is one of the largest and most distinguished examples of Second Empire architecture in the town of Huntington. It also reflects the mid-nineteenth-century remodelling of earlier houses and is tied to the Burr family, early Commack settlers who became successful horse breeders and trainers.","narrative":"Set on a three-acre lot along Burr Road in Commack, this two and one-half story, seven-bay shingled house began around 1830 as a typical three-bay, side-entrance farmhouse built for Smith Burr, a third-generation member of the Burr family in the area. His son Carll, who continued the family practice of raising and training trotters, remodelled it between 1881 and 1885 in a local version of the Second Empire style. The roofline carries a mansard roof with bracketed eaves and a denticulated cornice, plus a flat-roofed belvedere. Windows have heavily molded surrounds, and a front porch rests on square columns. Behind the house stand a c. 1890 five-bay barn and a c. 1920 cottage, both of which preserve the estate-like agricultural setting. The property was listed for its architectural quality, its high degree of integrity, and its link to a locally prominent horse-breeding family.","period_of_significance":null,"architect_builder":null,"architectural_style":"Second Empire","criteria":[],"status_note":"Listed as in good condition and still used as a residence. The form notes no known threats, a c. 1950 addition of asbestos shingles, and a barn and cottage that still contribute to the property.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:44.616432-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/85002502.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85002502/3d9ea4fae3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85002502/3d9ea4fae3-1600.webp","licence":"CC BY-SA 3.0","author":"AJW1188","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Carll_S._Burr_Mansion.jpg\" rel=\"noopener\">AJW1188</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Carll_S._Burr_Mansion.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314847","wikipedia":"https://en.wikipedia.org/wiki/Carll_S._Burr_Mansion","wikidata":"https://www.wikidata.org/wiki/Q5041433"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/suffolk-county/burr-carll-s-mansion-85002502/"}
